A team of archaeologists in Mesopotamia (we can guess, the film just describes it as "Asia" which doesn't really narrow things down much) discover some ancient writings near the top of a mountain. Dr Bentley (John Agar) and his buddies are trapped under a glacier after an earthquake and discover a lost Sumerian civilisation which has existed underground for the last five thousand years!
The Sumerians exist on mushrooms and enslave savage reptilian like creatures. They also have a harsh and deadly regime where surplus population are sacrificed to Ishtar. Bentley poses as a herald of Ishtar and has a crush on slave girl Adad (Cynthia Patrick). Meanwhile, the high priest (Alan Napier) is suspicious of Bentley and plans to get rid of him...
Although a fairly basic film in many ways i loved the idea of this film, being a historian myself (even if their "Sumerian" script is actually Egyptian hieroglyphs at times not cuneiform!) Lost worlds are always fun, more than the real world indeed.
